GSM/UMTS success to marginalize other wide-area wireless technologies
Posted: 14-Sep-2006 [Source: 3G Americas]

[New white paper from 3G Americas says GSM/UMTS "has an overwhelming global position" and is set to marginalize other wide-area wireless technologies.]

Bellevue -- "GSM/UMTS has an overwhelming global position in terms of subscribers, deployment, and services. Its success will marginalize other wide-area wireless technologies," states the Rysavy Research white paper published by 3G Americas today. Prepared by independent research consultant Peter Rysavy, Mobile Broadband - EDGE, HSPA and LTE carefully reviews the promises made on the technical features, benefits and delivery status of wireless mobile services, particularly through the GSM family of technologies -- EDGE, UMTS/HSPA and 3GPP Long Term Evolution (LTE).

The white paper provides an extensive overview of the deployment status, technical capabilities and workings of current and future mobile wireless technologies, specifically, on EDGE, UMTS/WCDMA, HSPA, HSPA Evolution and LTE, with comparative information on alternative technologies including CDMA2000 EV-DO and WiMAX802.16e-2005. This includes an in-depth technical examination of the different wireless technologies with respect to performance and spectral efficiency. The proof points in the research, developed as a collaborative effort with consensus among the members of 3G Americas, representing operators and leading manufacturers of devices, infrastructure, chipsets, and other elements of the eco-system, fully support the strength and merits of the GSM evolution over other technologies.

"UMTS/HSPA technology and its evolution beyond 3G will compete with any and all mobile wireless technologies available today and in the near future," stated Chris Pearson, President of 3G Americas. "The GSM/UMTS ecosystem, serving more than 2 billion customers, is unmatched by any other mobile wireless technology and is possibly unmatched by any other communication technology ever. The business and economic advantages of serving such an expansive customer base, coupled with the technical advancements of HSPA and LTE, provide the combination that will win over other wide-area mobile wireless technologies."

Pearson continued, "Whereas other wireless technologies show great potential on paper, UMTS has global commercial deployments providing customers mobile broadband service today."

Some of the key observations and conclusions of the Rysavy Research white paper include:

* The 3GPP roadmap provides operators maximum flexibility in evolving their networks through three avenues, each coexisting harmoniously with the others: the continued evolution of GSM system capabilities, UMTS evolution and 3GPP LTE.

* EDGE technology has proven extremely successful and is widely deployed on 160 GSM networks in 91 countries. Improvements to the EDGE standard will provide the capability to more than quadruple current EDGE throughput rates.

* The high spectral efficiency of HSPA provides operators an efficient high-capacity network for all services. In the longer term, UMTS/HSPA provides for a clean migration to packet-switched voice.

* VoIP with HSPA will eventually add to voice capacity and reduce infrastructure costs. In the meantime, UMTS enjoys high circuit-switched voice spectral efficiency and can combine voice and data on the same radio channel.

* In current deployments on 51 networks worldwide today, HSDPA users under favorable conditions regularly experience throughput rates well in excess of 1 Mbps that will increase with planned enhancements of HSDPA.

* HSUPA users under favorable conditions will experience peak achievable rates close to 1 Mbps in the uplink when the technology is commercially deployed in 2007.

* Continual HSPA enhancements are planned. Beginning with enhanced uplink performance, advanced receivers in the mobile and in the base station, and then MIMO, these improvements will extend HSPA capability even further.

* The HSPA Evolution systems could match OFDM-based approaches in spectral efficiency and peak data rates in 5+5 MHz radio allocations through the use of equalizers and interference cancellation techniques.

* The 3GPP LTE work item continues to make significant progress with expected peak downlink speeds of 100 Mbps and peak uplink speeds of 50 Mbps in 20 MHz channels.

Peter Rysavy, President of Rysavy Research, stated, "Mobile WiMAX is a hot topic story at the moment. Yet, in fact, the GSM technical migration to Evolved EDGE, HSPA, HSPA+ and LTE will be the compelling realization for most operators worldwide as they provide new data application services to their more than 2 billion customers." He added, "This white paper provides a detailed analysis of the various mobile wireless broadband technologies that justifies and supports this conclusion."
